To design and develop smart grid its need to innovate smart appliances which are more reliable and efficient. To contribute in smart work we are going to design a cost effective solution in distribution transformer, to protect it from thermal overload. In India the maximum distribution transformer is damaged due to overloading, but still there is no any smart protection is applied for it due to its high cost. One other advantage of newly designed Protection system of transformer is it having inbuilt thermal overload protection in distribution transformer. Every distribution transformer having star connected secondary winding. As concentrate on that neutral point we design contactor based system to disconnect neutral point when thermal overload is occurring.
